Kestrel Pocket Weather Meters and HORUS Vision have partnered to provide a powerful shooting tool that combines the critical environmental data and targeting software solutions required for precision shooting -- all in one four-ounce pocket-sized unit. Previously, shooters would need to obtain environmental data from a Kestrel meter and then input that data into a PDA loaded with HORUS Ballistics Software. Now, the Kestrel Ballistics Weather Tracker with HORUS Ballistics Software contains all of the necessary data and solutions in one device to minimize user workload and distraction. Plus, the Kestrel meter is IP67 waterproof and MIL-STD-810F rugged, allowing users to avoid the expense and weight of a ruggedized PDA.

The unit allows users to load and customize multiple guns and rounds from the extensive proprietary HORUS database. Simple, intuitive screens allow the user to create up to five targets customized for location, distance, direction, declination and winds. The Kestrel meter's highly accurate measuring and averaging of wind and digital compass for target bearing and wind direction assists in defining the target winds. Once these parameters are set, the Kestrel meter takes over - tracking the current met data and automatically updating the firing solution using HORUS Ballistics Softare advanced proprietary algorithms and taking coriolis and spin drift into account. No additional user input is required.

The HORUS Ballistics Software that comes with the 4500 is the civilian version. The military version of the HORUS Ballistics Software is only available via special GSA contract to officials with the correct security clearance. The software that ships with the Kestrel 4500 with HORUS Ballistics Software is version 3.0. It is possible to upgrade the firmware as new versions become available, however it will need to be returned for firmware updates.
